Notes:

The heating for Oxygen Sensor Probes behind Three Way Catalytic Converter (TWC) is not switched on immediately at
engine start, but when the calculated exhaust gas temperature drops below 308 C (586 F) ( Read measuring value
block, display group 42, channel 1). The malfunction "P1105 / 17513" is set as soon as the probe heater is switched on (the vehicle must be driven approx. 60
sec. under load) and the heating current is greater than 10 A for longer than 80 ms.
